Cook’s Notes and Secrets

For the best results when making Creamy Chicken Mushroom Potato Casserole, consider these tips:

Ensure even cooking by cutting potatoes into uniform pieces.
If using frozen chicken or turkey, make sure to fully cook it before adding it to the casserole.
Let the dish sit for a few minutes after baking, which helps it set and makes serving easier.
Use a meat thermometer to confirm the chicken reaches an internal temperature of 165°F for safety.
For an extra crispy topping, broil at the end for a few minutes, keeping a close watch to prevent burning.
